Jetpack plugin removed images from my website

I am using the sketch theme and I wanted to upload a logo for my site. It seems that the only way to do this with this theme is by activating Jetpack, but once I do this it automatically deletes the image from my sidebar, which I can’t seem to prevent from happening. Is there a way of activating Jetpack, so that I can upload the logo, without it deleting images from my site?
Thank you.
